Senior Customer Success Manager

Ready to grow your CSM career in a fast-moving, creative industry?

As a Senior Customer Success Manager, you'll work directly with our most valuable customers, guiding them from first collaboration to long-term results. Your role is to make sure they get the most value from our (AI) technology, services and their partnership with our freelance network. You’ll focus on building long-term relationships, lead the execution of tailored solutions, and own retention and upsell opportunities. You’ll be working in a fast-growing segment of our business, and we’re looking for someone who can think creatively, act proactively, and thrive in a dynamic environment.

Welcome to Contentoo!

We’re all about opportunities, positivity, and enjoying the journey. Use your experience to help brands deliver better content, faster.

What you’ll do

• Build strong working relationships with a set of high-value clients. Align their goals with Contentoo’s services, check in regularly, and solve issues before they grow.

• Work with teams across onboarding, talent, operations, and product to ensure smooth setup and collaboration between clients and freelance creators.

• Become an expert in Contentoo’s platform. Use it to improve the customer experience, find new opportunities, and help clients get the most from the tools.

• Keep your accounts healthy and growing by building relationships with multiple stakeholders in each company. Spot chances to expand into new teams or offer new services.

• Take ownership of your accounts. Lead renewals, spot upsell opportunities, run Executive Business Reviews, and create success plans that show long-term value.

• Support newer CSMs and help improve how the CS team works by sharing clear, actionable ideas with the Head of CS.

• Work with teams such as Finance, Marketing, and Legal to continually improve the overall customer experience.

What you’ll bring

• You are fluent in English, both verbally and in writing; Dutch is a bonus.

• You are a positive, proactive professional with at least 4 years of experience in a commercial, customer-facing, consulting, or partnership management role.

• You have a proven track record of managing high-revenue books of business and/or enterprise customers, and you’re comfortable building strong, trust-based relationships with senior stakeholders.

• You thrive in a fast-paced, evolving environment and are a true self-starter with a hands-on, commercial mindset. You’re not afraid to roll up your sleeves, think creatively, and make the most of the resources available to you.

• Your time-management skills and attention to detail are excellent, and you enjoy working on multiple projects simultaneously.

• You use AI to save time, find insights, and support your customers — and are curious about what’s next.

• You’re comfortable digging into data to understand customer behaviour and needs, and you have the basic analytical skills to translate insights into action.

• You combine a product mindset with hands-on platform knowledge — giving demos, supporting customers with confidence, and proactively suggesting product improvements to enhance the customer experience.

• A basic understanding of the content marketing landscape is preferred; bonus points if you’ve worked with or within a marketing team!

A day in the life

It’s Friday. You kick off the day with a team recap, sharing wins, challenges, and moments from the week. Your highlight: a strong planning call with one of your biggest customers. You aligned with their regional marketing team on upcoming content as they prepare to expand into 10 new markets. They have topic ideas but need help briefing and executing. After the call, you check timing and capacity with your freelance Content Managers, then send the customer an update, including budget and a first plan.

Next is your weekly check-in with your Customer Ops Specialist to review enterprise accounts. A junior CSM joins to shadow, and you’ve been helping them fix a gap in a team process. You walk through your approach to delivery tracking, using a real account example to discuss risks, escalations, and clear communication. It’s a practical learning moment that also sharpens the team’s workflow.

Later, you join an onboarding kickoff call with a new enterprise customer, alongside the Onboarding Manager and Customer Ops. While they lead the intro, you’re there as the future account owner — asking questions, building rapport, and learning how the customer works. Afterwards, the three of you meet to plan the setup: team roles, workflow, and prep for the first projects. You spot a possible product issue and book time with Product to explore ways to streamline delivery at scale.

In the afternoon, you prep for next week’s Executive Business Review with a long-time customer. They’re bringing a senior stakeholder, and your Head of CS will join too. You make sure the deck shows clear results: what’s worked, what we’ve learned, and where we can grow. You update the budget, check the numbers, and review everything with your Team Lead before sending it to the customer for feedback.

You wrap the day with the team, sharing a drink or cake at the bar or on the rooftop, chatting through the week, and celebrating wins.
